<h3 class="section">4.3 Technical Specification 29113 Status</h3>

<p>GNU Fortran supports some of the new features of the Technical
Specification (TS) 29113 on Further Interoperability of Fortran with C.
The <a href="https://gcc.gnu.org/wiki/TS29113Status">wiki</a> has some information
about the current TS 29113 implementation status.  In particular, the
following is implemented.
</p>
<p>See also <a href="Further-Interoperability-of-Fortran-with-C.html#Further-Interoperability-of-Fortran-with-C">Further Interoperability of Fortran with C</a>.
</p>
<ul>
<li> The <samp>-std=f2008ts</samp> option.

</li><li> The <code>OPTIONAL</code> attribute is allowed for dummy arguments
of <code>BIND(C) procedures.</code>

</li><li> The <code>RANK</code> intrinsic is supported.

</li><li> GNU Fortran&rsquo;s implementation for variables with <code>ASYNCHRONOUS</code>
attribute is compatible with TS 29113.

</li><li> Assumed types (<code>TYPE(*)</code>.
